Power limitations in BARITT devices
(Elsevier, 1976-09)
The results of a large-signal numerical simulation of the BARITT device using a single-carrier model are given to illustrate the basic transport mechanisms involved in the device. The results of existing first-order small- ...
Interferometric gratings with phase correction
(Elsevier, 1974-06)
A technique for producing diffractive optical elements uses holographic methods to incorporate into the recorded fringe pattern a correction factor for the phase defect of the substrate.
Thick grating analysis of interferometrically produced waveguides
(Elsevier, 1975-06)
The thin grating decomposition method of thick grating analysis is used to analyze guiding effects in thick phase gratings having sinusoidal refractive index modulation.
Instabilities and small-signal response of double injection structures with deep traps
(Elsevier, 1972-12)
The small-signal response is discussed for double injection structures heavily doped with deep recombination centers. The discussion is based on an exact small-signal linearization of the nonlinear equations describing the ...
Rainbow holographic interferometry
(Elsevier, 1978-05)
A one-step rainbow holographic process is applied to holographic interferometry. Experimental demonstrations of double exposure and time-average interferograms are included. Comparison is made with the conventional holographic ...
Holography with non-coherent light
(Elsevier, 1973-12)
A new technique of making holograms with non-coherent light has been demonstrated using continuous-spectrum white light zirconium arc source. Such a technique, employing diffraction gratings as beam splitters and beam ...
Phase correction in holographically produced gratings
(Elsevier, 1974-10)
Several technques for producing holographic optical elements that are free from the inherent phase errors of their substrate irregularities are given.
